NCurses Display Manager (NCDM) is, well, a display manager written in python. It also manages commandline sessions, so display or desktop probably is not the right word for the D part of the acronym. However, it is very much in an alpha state, so if you want to test it, put it on a computer where you're fine with it making mistakes.
- Disable root login if needed
- Allow select users to only log in once
- Allow customization of session list on a per user basis. See sys.cfg for more details.
- List CLI and GUI sessions in *.csv files with the format "Name","Command".
- Autodetect available GUI sessions based on what is in /usr/share/xsessions and /etc/X11/sessions.
- PAMless authentication.
- List active sessions and switch between them.
- Configure commands for hibernate, suspend, shutdown, and restart buttons
- Color scheme configuration
- Optional FBTerm and Consolekit support
- Custom banner to welcome users
- Always has an option for a login shell if cli.csv does not exist.
- Allow setting background image for NCDM if fbterm is told to be used
- Log program operation (useful for detecting bugs)
- Core python modules: crypt, spwd, pwd, grp, os, re, subprocess, platform, glob, csv
- kbd (for opening a virtual terminal and launching the cli session on there using openvt)
- Port to python 3 once kinks are worked out.
- Register sessions programatically with python-utmp? So far the commented out code using python-utmp doesn't work (http://korpus.juls.savba.sk/~garabik/software/python-utmp/README.txt)
- Add custom markup support for banner
- Add more places for theming?
- Remote login support? Pretty iffy.
